M.2
ArmourDrive™ PX Series modules (referred to as“M.2 ArmourDrive” in this factsheet) are highperformance, high-reliability solid state drives. They
combine 64, 128, 256 or 512 GBytes, or 1 or 2 TBytesof NAND flash memory with an advanced Serial ATA(SATA) controller on a printed circuit board (PCB).

The SATA SSD controller with built-in advanced
NAND management firmware communicates with thehost through the standard SATA protocol. It does not
require any additional or proprietary software such as
the Flash File System (FFS) and Memory Technology
Driver (MTD). The firmware effectively optimizes theuse of NAND flash memory’s program/erase (P/E)
cycles and minimizes write amplification.
M.2 ArmourDrive’s advanced NAND management
technology improves endurance, enhances data
security and helps prevent data corruption during
unexpected power failure events. This innovativetechnology combines robust NAND controller
hardware error correction capabilities with advanced
wear-leveling algorithms and bad block management
to improve data reliability and significantly extend thelife of the product.

M.2 ArmourDrive is ideal for applications that require
removable form factor and more reliable data storage.
SATA M.2 solid state storage technology is widelyused in industrial computers, test and measurement
instrumentation, multi-functional printers, medical
equipment, security and surveillance systems,
network servers and digital signage. These removablesolid state drives (SSDs) surpass traditional hard diskdrives (HDDs) in their small size, security, reliability,ruggedness and low power consumption.

GENERAL DESCRIPTION

Each M.2 ArmourDrive module integrates a SATA SSD controller with NAND flash multi-chip packages. Refer toFigure 2-1 for the M.2 ArmourDrive block diagram.

1.1

1.1.5Optimized M.2 ArmourDrive

Power Interrupt Data Protection is a mechanism tohelp prevent data corruption during unexpected power
failure events. Enhanced data integrity is supported by
the controller’s advanced firmware during abnormal
power loss. The controller proactively optimizes theamount and stay time of the “in-flight” data residing inthe cache. To ensure there is no data loss risk causedby power cycling, the controller sends anacknowledgement to the host only when the incoming
data is fully committed to the NAND flash.

The heart of M.2 ArmourDrive is the SATA SSDcontroller, which translates standard SATA signals
into flash media data and control signals. The
following components contribute to M.2 ArmourDrive’soperation.
1.1.1

Microcontroller Unit (MCU)

The MCU translates SATA commands into data andcontrol signals required for flash media operation.
1.1.2

Internal Direct Memory Access (DMA)

1.1.6

M.2 ArmourDrive uses internal DMA allowing instantdata transfer from/to buffer to/from flash media. This
implementation eliminates microcontroller overhead
associated with the traditional, firmware-based
approach, thereby increasing the data transfer rate.
1.1.3

Error Checking and Correction (ECC)

The ECC technology uses advanced algorithms todetect and correct errors, ensuring data integrity andextending the SSD lifespan.
1.1.7

Power Management Unit (PMU)

Multi-tasking Interface

The multi-tasking interface enables concurrent Read,
Program and Erase operations to multiple NAND flashmedia.

The PMU controls the power consumption of M.2
ArmourDrive. The PMU dramatically reduces thepower consumption of M.2 ArmourDrive by putting thepart of the circuitry that is not in operation into sleep
mode.

1.2Advanced NAND Management

M.2 ArmourDrive’s controller uses advanced wearleveling algorithms to substantially increase thelongevity of NAND flash media. Wear caused bydata writes is evenly distributed in all or selectblocks in the device that prevents “hot spots” inlocations that are programmed and erased
extensively. This effective wear-leveling techniqueresults in optimized device endurance, enhanced
data retention and higher reliability required bylong-life applications.

The Flash File System handles inadvertent powerinterrupts and has auto-recovery capability to ensure
M.2 ArmourDrive firmware integrity. For regular power
management,
thehostmust
send
anIDLE_IMMEDIATE command and wait for command
ready before powering down M.2 ArmourDrive.
1.1.4

Power Interrupt Data Protection

Embedded Flash File System

The embedded flash file system is an integral part ofM.2 ArmourDrive. It is integrated in the controller’s
firmware that performs the following tasks:
1. Manages and optimizes the data access of flash
media
2. Provides flash media wear leveling to spreadthe flash writes across all memory address
space to increase the longevity of flash media3. Keeps track of data file structures
